Abstract :
In this paper we propose the use of chirp managed lasers (CML) as cost-effective downstream transmitters in next generation access networks. The network simplicity and an optical power budget of 36 dB obtained with phase-shift-keying direct modulation of CML proves that the proposed solution could be a strong candidate for future WDM-PONs.
